Hi. I just joined this community. My name's Patty and I'm a Project Manager (Hi, Patty). I like obscure trivia and photos of dogs wearing costumes.

My reason for posting here is that I'm working on a project to implement CAPTCHA, and I noticed that LiveJournal has a nifty little captcha that comes up when you try posting to a journal that doesn't allow anonymous posting and you aren't logged in. The specific aspect of this in which I'm interested is that, if you're visually impaired, you're instructed to type "AUDIO" into the text field for an audio test instead of an image test.

Is the code that makes this happen part of what is open source? If so, where can I peek at it?
